The invention discloses a radiating structure of a high power density variable-frequency converter and belongs to the technical field of liquid cooling for motor variable-frequency controllers. The radiating structure comprises a water-cooling radiator in vertical symmetry. Radiating baseplate inner radiating fins, a perforated heat exchange partition, local protrusion inner radiating fins and a heat exchange surface are arranged on the symmetrical surface of the water-cooling radiator sequentially from inside to outside. A heating element is in a distribution structure of vertical symmetry. A high heat generation power device is installed on local protrusions. Small-sized devices are disposed in slits among the local protrusions. A device low in heat generation is disposed on a radiating baseplate. The radiating structure is compact in structure, high in radiating area utilization rate and high in radiating efficiency, and meets the heat dissipation requirement of high power density variable-frequency controllers in special vehicles.
